Pure Water Oceanside-Potable Reuse-Sustainability Sustainble Building Week

Water Authority Board Supports Regional Potable Reuse Projects

/in , /by

The San Diego County Water Authority’s Board of Directors today unanimously approved a formal resolution reaffirming its longstanding support for potable reuse and water recycling projects developed by local member agencies across the region.

“Projects such as Pure Water San Diego, Pure Water Oceanside and the East County Advanced Water Purification Project are critical to the continued development of local water sources that help sustain the region’s 3.3 million residents and $245 billion economy,” said Water Authority Board Chair Gary Croucher. “The Water Authority has long supported water reuse and recycling projects, and we will continue to collaborate with member agencies in developing these vital local resources.”

Water supply diversification

For more than two decades, the Water Authority has promoted the advancement of water recycling and reuse in San Diego County as part of the region’s water supply diversification and reliability strategy.

The agency has sponsored and supported legislation to speed the development of potable reuse regulations in California, and has worked as an active member of the WateReuse Association to help shape the statutory and regulatory framework for potable reuse in the state. And Water Authority investments in high-priority, highly reliable water from the Colorado River support the development of local resources by delivering a low-cost baseload of water that can be recycled and repurified.

Potable reuse project funding

In addition, the Water Authority has advocated for robust funding in state bond measures, including seeking the inclusion of up to $500 million to expedite potable reuse and advanced water treatment projects in a legislative bond measure targeted for the November 2022 ballot. The Water Authority also helped secure nearly $500 million for local projects from the Metropolitan Water District of Southern California in 2019 and 2020, and most of that money was for potable reuse.

Potable reuse relies on advanced treatment technologies to produce a high-quality drinking water that is locally controlled, drought-resilient, and reduces wastewater ocean discharges. Every gallon of recycled or repurified water reduces the need to import or develop other supplies.

Recycled water, potable reuse projects under construction

Approximately 33,000 acre-feet of recycled water is expected to be reused within the Water Authority’s service area annually by 2025. The volume is expected to continue growing as new and expanded potable reuse plants come online. They are projected to produce more than 112,000 acre-feet per year of new drinking water supplies by 2045, enough to meet nearly 18% of the region’s future water demand.

Two of the first three potable reuse projects are now under construction in San Diego County:

A third project, the East County Advanced Water Purification Program, a combined effort by the City of El Cajon, Padre Dam Municipal Water District, the County of San Diego, and the Helix Water District, is in the design/pre-construction phase.

COVID-Water Debt-Debt Relief-Coronvirus

Agencies Seek Relief Funds to Cover Delinquent Water Bills

/in , /by

Water agencies across the region are seeking help from the County of San Diego and the 18 incorporated cities in the county to provide essential financial relief for households throughout the county that are facing growing water bill delinquencies due to the COVID-19 pandemic.

The water agencies are asking that the cities and the county allocate state and federal COVID relief funds to provide water bill offsets for financially strapped residents.

Local water suppliers “have not received any COVID-related funding assistance to help address the substantial water debt held by residents of our communities that would help to provide much-needed relief to water ratepayers,” according to mid-February letters from water officials to county and city leaders.

Helping with water debt repayment a “high priority”

“It’s very important to prioritize helping those San Diegans first who are at greatest risk of serious economic harm as a result of the pandemic so they can avoid exacerbating their dire financial conditions as the pandemic lingers,” said the letters. “We believe that helping residents with water debt repayment should be one of those high priorities, and we look forward to working with you in the coming weeks to ensure that COVID relief funds that you receive from the State or through direct federal allocation are shared in the same spirit of partnership that we reach out to you today.”

The letters were signed by the San Diego County Water Authority and 12 of its member agencies: the cities of Del Mar, Escondido and Oceanside, Sweetwater Authority, Otay Water District, Olivenhain Municipal Water District, Helix Water District, Padre Dam Municipal Water District, Vallecitos Water District, Vista Irrigation District, Rincon del Diablo Municipal Water District, and Valley Center Municipal Water District. California American Water, which serves Coronado and Imperial Beach, also signed the letters.

Debt crisis

“The water suppliers would commit to see that any resources received are allocated directly to offset water bill delinquencies that have accumulated since the beginning of the COVID pandemic, or that have materially increased over the past 10 months,” said the letters.

“This accumulation of debt – along with other utility, rent, and unpaid bill debt – threatens to create a long-term and enveloping household economic crisis for thousands of San Diegans. While the water supplier community has worked closely with our Congressional partners and the Newsom Administration, there has not been COVID financial relief forthcoming directly to water suppliers to help customers with the growing crisis of household water debt.”

Pandemic-related water bill debt

Recent reports show that nearly 70,000 households in San Diego County have accumulated pandemic-related water bill debt. It is estimated that San Diego County customers alone owe as much as $50 million in water bill payments that are currently delinquent and in arrears as a direct result of the pandemic.

$1 billion in unpaid water bills

The State Water Resources Control Board recently released the results of a statewide survey of water systems which found that California residents owe an estimated $1 billion in unpaid water bills that have accumulated since the Governor issued COVID-related emergency orders in early April 2020.

Under California law, water agencies are prohibited from taking money from reserves to pay off the debt for ratepayers behind on their bills.  “As a result, an independent source of funds, separate and apart from rate revenue, is necessary to provide the types of rate offsets and relief that are so desperately needed by our customers,” the letters state.

The San Diego County Water Authority and its 24 retail member agencies do not make a profit. Rather, rates and charges support the infrastructure and supply that provides the safe, reliable water that fuels the region’s economy and quality of life.

Water Main Breaks Decline in San Diego for Fourth Year in a Row

/in , /by

Increased maintenance efforts by the City of San Diego of its water system infrastructure is paying off for ratepayers. For the fourth year in a row, the number of water main breaks has decreased in the City of San Diego. Thirty-three water main breaks were reported in 2020, the lowest total in more than 15 years.

The City credits its aggressive multi-year program to replace aging pipelines for bringing the numbers far below the peak of 131 breaks in 2010.

“The City’s Public Utilities Department has worked very hard to improve the reliability of our water system infrastructure,” said Shauna Lorance, director of public utilities. “Our citizens benefit greatly from fewer main breaks because it means less water loss and lower emergency repair costs.”

San Diego’s continuing program to replace old cast iron water mains has played a major part in the decrease in breaks. Some cast-iron pipes had been in service for more than a century. Since 2013, the city has replaced approximately 180 miles of water pipelines. By 2025, the last 55 miles of cast iron water mains are scheduled to be replaced with water mains made of durable polyvinyl chloride.

Water infrastructure maintenance programs also deliver a benefit to our region’s overall economy. According to the Economic Policy Institute, $188.4 billion spent on water infrastructure investments over five years would yield $265 billion in economic activity and create 1.9 million jobs.

“Improving and maintaining our water infrastructure is an important part of our commitment to serving our customers,” said Lorance. “We will continue to provide reliable water services our customers deserve.”

City of San Diego public utilities crews routinely oversee preventative maintenance work to help determine potential leaks and breaks before they occur. Private contractors have completed the bulk of the pipeline replacement projects under the direction of the City’s Engineering and Capital Projects Department.

Landfalling Atmospheric Rivers Increase in First Quarter of Water Year 2021 Over 2020

/in , /by

A Scripps Center for Western Weather and Water Extremes report shows that more atmospheric rivers have made landfall over the U.S. West Coast in the first four months of Water Year 2021 compared to the previous period in 2020.

The four months of Water Year 2021 experienced a total of 35 landfalling ARs over the U.S. West Coast, six more than the first four months of Water Year 2020, according to the CW3E quarter year summary released February 11.

Key takeaways from the CW3E update on atmospheric rivers

• The first four months of Water Year 2021 experienced a total of 35 landfalling ARs over the U.S. West Coast, 6 more than the first four months of Water Year 2020.
• Water Year 2021 also experienced more than twice as many strong or greater ARs (14) compared to Water Year 2020 (6).
• While Water Year 2021 saw more ARs in its first 4 months compared to Water Year 2020, a large majority of those ARs were
strongest over the Pacific Northwest (Oregon and Washington).
• The average landfall latitude thus far in Water Year 2021 was 45.9°N compared to 43.9°N during the first half of Water Year 2020.
• The lack of landfalling ARs over Southern California and Baja California has resulted in much drier conditions over the southwestern U.S. compared to WY 2020.

Atmospheric River-NOAA-WNN-CW3E

A partnership with the San Diego County Water Authority and the Scripps Institution of Oceanography at UC San Diego seeks to optimize water management to better predict atmospheric rivers before, during, and after those seasonal storms.

In August 2020, Scripps Center for Western Weather and Water Extremes (CW3E) launched the Water Affiliates Group, which brings together cutting-edge science and hands-on water industry experience to enhance reservoir operations in light of the changing climate. The Water Authority has a long-running alliance with Scripps and is among six founding water agencies statewide.

CW3E and its partners will share and support best practices in forecast-informed reservoir operations, increase research around atmospheric rivers and droughts, and develop strategies for mitigating flood risk and increasing water supply reliability.

The plants are thriving at Helix Water District’s demonstration landscape just eight months after the project was completed. The WaterSmart plants at the District’s administration office in La Mesa beautify the neighorhood while inspiring people to install sustainable, WaterSmart landscaping.

“Everything is growing in beautifully,” said Helix Water District General Manager Carlos Lugo. “We started with smaller plants to reduce costs and planned for growth. We’re happy to share this resource with our customers and community.”

Demonstration landscape includes water-wise gardens

The demonstration landscape includes three unique water-wise gardens on the streets around the building, including a Mediterranean garden on University Avenue, a desert landscape on Lee Avenue and a California native landscape along the building’s main entrance on Quince Street. Each garden started with smaller plants of varying colors, flowers and textures.

Plants provide wildlife habitat

The plants in all three of the gardens are adapted to San Diego’s climate and need half to a fifth of the water that a traditional lawn needs. In addition to requiring less water, WaterSmart landscapes also require less maintenance and provide habitat for local wildlife like honeybees, birds and butterflies.

In each garden, plant markers provide the name of each plant and a QR code, which when scanned with a smartphone, provide each plant’s name, sun and water needs, mature size and photo.

Customers can also use the district’s interactive webpage to make a list of their favorite plants and download each garden’s design plan. Information on efficient irrigation and rebate programs is also available.

The project was completed in June 2020 and partially funded through a grant from the Metropolitan Water District of Southern California.

Helix Water District provides water treatment and distribution for 277,000 people in the cities of El Cajon, La Mesa and Lemon Grove, the community of Spring Valley and areas of Lakeside – east of downtown San Diego. Helix is also a founding member of The Water Conservation Garden, a nearly six-acre water-wise demonstration garden in El Cajon.

Approximately 90% of Oceanside’s drinking water is imported. Pure Water Oceanside will create three to five million gallons of drinking water each day, enough water to provide 32% of the City of Oceanside’s water supply.

The water purification process uses reverse osmosis and advanced oxidation to create safe drinking water. The technology removes pharmaceuticals, chemicals, hormones, microplastics, and personal care products.

The project protects sensitive ecosystems by reducing the amount of water siphoned by imported water sources. It decreases the amount of recycled water discharged into the ocean, and uses half the energy needed to transport imported water, reducing greenhouse gas emissions.

Residents are kept up to date on construction impacts to streets and other infrastructure through several outreach efforts including an interactive construction map, detailed online schedule, regular newsletters, and virtual open house presentations live on the City of Oceanside’s YouTube channel, offering residents the opportunity to ask questions.

Precipitation-Snowpack Survey-Sierra Nevada-DWR

Precipitation Below Average in California

/in , /by

Precipitation is below average in California for the current water year. Despite recent storms that increased the statewide Sierra Nevada snowpack to 70% of average to date, the state is experiencing its second consecutive below average year for rain and snow. The water year starts on October 1 and ends September 30.

The Department of Water Resources Feb. 3 conducted the second manual snow survey of the season at Phillips Station. The manual survey recorded 63 inches of snow depth and a snow water equivalent, or SWE, of 17 inches, which is 93% of average for that location, according to the DWR. The SWE measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast.

“The recent blast of winter weather was a welcome sight, but it was not enough to offset this winter’s dry start,” said DWR Director Karla Nemeth. “While there is still a chance we will see additional storms in the coming weeks, the Department and other state agencies are preparing for the potential for a second consecutive year of dry conditions.”

La Niña-Sierra Nevada-snowpack-climate-snow survey

Below normal precipitation is favored throughout most of the southern tier of the United States in late February to early March, according to the National Weather Service Climate Prediction Center. La Niña conditions remain over the Pacific Ocean.

Precipitation below normal

Statewide snow survey measurements reflect those dry conditions. Measurements from DWR’s electronic snow survey stations indicate that statewide the snowpack’s SWE is 12.5 inches, or 70% of the February 3 average, and 45% of the April 1 average. April 1 is typically when California’s snowpack is the deepest and has the highest SWE.

“The recent atmospheric storms have brought rain and snow to the northern Sierra Nevada, but conditions are still well below normal,” said Goldy Herbon, San Diego County Water Authority senior resources specialist.

Following last year’s below average water year, northern California is now experiencing its second straight water year of below average precipitation.

Colorado River Basin

Another source of the state’s water supply, the Colorado River Basin, isn’t faring much better. The water year 2021 precipitation at the end of January for the Colorado River Basin is 66% of normal, according to the U.S. Bureau of Reclamation.

Precipitation totals to date are behind historical averages for two of the main sources of San Diego County’s supply, with two months to go in the winter season but, a couple of atmospheric rivers can change that quickly.

“The San Diego region will have a plentiful and reliable source of water due to actions taken by the Water Authority and its 24 member agencies to diversify the water supply,” said Herbon. “Continuing efforts to expand supply sources, including desalination, water reuse, and recycling, will ensure that the water needs are met for the region’s 3.3 million people and its $245 billion economy.”

Fall 2020 was extremely dry, especially in the Sierra Nevada, and follows last year’s below-average snow and precipitation, according to the DWR. With only a couple months remaining in California’s traditional wet season, DWR officials say Californians should look at ways to reduce water use at home.
